RAILROAD-TIE.

Specification of Letters Patent.

Patented Mar. 1'7, 191%.

Application filed September 11, 1911. Serial No. 648,821.

To all whom it may concern Be it known that I, Grouse M. Launnn- MILOII, a citizen of the United States, residing at Derry Church, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improve ments in Railroad-Ties, of which the following is a specification.

My invention relates to new and useful improvements in railroad ties.

The objects of my invention are to provide a railroad tie which is economical, practical and of universal application to any type of rails, whether of steam or trolley. And further objects are to provide a combination tie, constructed of metal and cement, or like material, which will liefirmly in the road bed, whether set in or laid on the surface, and give to the rails sufiioient elasticity, and at the same time is strong and durable, and from which the rails can be easily removed, replaced or tightened as required. I acc0 nplish these objects by means of the device illustrated in the accompanying drawmgs, in which-- Figure l is a plan view of a series of t es showing the manner of applying the rails to the same. Fig. 2 is a cross sectional view of a tie. Fig. 3 is a longitudinal sectional view at the point where the rails cross the ties. Fig. 4, is a perspective of a portion of the metallic skeleton showing the open end and side. Fig. 5 is a detail of the washer which secures the rail to the tie.

Similar figures refer to similar parts throughout the several views.

Referring specifically to the drawings, 1 is an ordinary railroad rail and 2 1s a cross sectional end of the same.

3 is a metallic, substantially rectangularly formed skeleton, with one side open, 4.. Th1s skeleton is of suitable thickness and dimensions for a tie, and is adapted to be filled with cement, or like material, in the construction of the tie, as hereinafter detailed. Each side of the said metallic skeleton is provided with a wedge shaped crnnp, 5, formed in the metal, and extending longitudinally the entire length of the skeleton, and nearer to the open side thereof, 4. It 1s also provided with openings, as at 6 and 7, through which bolts are inserted in the construction and operation of the tie, as hereinafter detailed. ()ther openings are provided, as at 8, in the sides of the skeleton, oppositely disposed, at and through the wedge shaped crimps, through which bolts may be inserted to hold the skeleton firmly against the cement filling, as well as preventing the skeleton from spreading and the filling from being cracked, injured or entirely destroyed. ihe crimps prevent the destruction and decomposition of the cement filling, and act as a resilient spring to the rails, giving elasticity thereto and reducing the jar to a minimum.

The open portion of the ties being placed downwardly, presenting the cement side to the road bed, prevents the tie from slipping or sliding, as it will adhere more closely to the bed than the iron, or wood tie, as now in use.

The bolts 99 have enlarged heads with oval outer surface, 9, and flat inner, adjacent to the cement filling in the tie, thus pre' venting wearing or loosening the cement as the car pass over the tracks. These bolts are suitable in size to pass through the openings 6, and extend sufficiently above the surface of the skeleton to engage the flanges of the rails, 1, holding the same-in position and preventing them from moving from side to side, or spreading, as the cars pass over, said bolt 9 aflording projecting members performing the function stated and the walls of their elongated shank portions are straight so that the rail may be positioned between them either through vertical movement of the rail or tie.

The bolt 10 is of the ordinary type similar to 99, and adapted to insertion in the opening 7 in the skeleton 3. It is provided to extend farther above the surface of the skeleton than 9-9, and sufliciently to permit a bur, as at 11, and a washer, as at 12, to be inserted thereon. The bur 11 is of the ordinary type, but the washer 12 is constructed practically rectangular in form, except that it is formed with one side extended or elongated, as at 13, sufficiently to extend over and engage the flange, 14, of the rail, 1, for the purpose of holding the rail securely on the tie. This extension 13 is provided on its lower side with a notch or cuta way portion, 15, of suitable dimensions to cover, or extend over the flange of the rail and hold it against the tie, thus allowing the bur 11 and the washer 12 to set sufficiently low as not to interfere with the wheels of the car in passing over the track. This notch or cutaway allows the washer to fit securely against the flange, its edges closely engaging the edge of the flange, givmg rigidity to the rail, preventing any side movement, as well as retainmg it down 7 against the tie, and as the bolts 6 are placed on either side of the rail, the washer holds it firmly between them. lVith this arrangement and novelty of construction, the rails can be easily removed, replaced or tightened by manipulation of the bur 11, which controls the washer 12, and it is not necessary to entirely remove the bur or washer or remove or insert a rail.

Cross bolts, 1616, are of the ordinary type, and are adapted to pass through the openings 8 in the skeleton 3. They are for the purpose of strengthening the tie and to prevent the skeleton from spreading, as well as assisting in retaining the filling material in position.

The bolts 9, l0 and 16, are inserted in the openings 6, 7 and 8, prior to filling the metallic skeleton 3, and as the cement, or like material, is poured into the skeleton into the open side 4:, it is allowed to harden with the bolts incased therein. In filling the skeleton the ends are closed with any convenient method to hold the composite material in the form until it is sufliciently set to allow removal.

In the use of the tie the open side is to be laid to the roadbed, with the bolts extending upwardly, and the washer and bur adjusted thereon as herein described, after the rails have been laid.

Having described my invention, what I claim is,

1. In a tie having a body, in combination with a rail passing thereover, fastening ing projecting members one on each side of.

the rail permitting posit-idiii-ngmofalw rail between them through vertical movementhf' either the rail or tie, the body having plastic material through which the'projeeting members extend, said material by adhesion with said membersfastening them in the tie.

2. In a tie having a body, in combination with a rail passing thereover, fastening means securing the rail thereto and means additional thereto serving as means to col rectly position the rail and tie for fastening and to relieve the fastening means of lateral strain, said f additional means comprising projecting members one on each side of the rail permitting positioning of the rail between them through vertical movement of either the rail or tie, the body having plastic material through and beyond which the projecting members extend, said members iaving elongated positions extending directly through the material and having heads bearing against the material at its under surface, the projecting members by adhesion with said members fastening them in the tie.

In testimony whereof I aflix my signature in presence of two witnesses.
